Prayer Request for Butch the Dog

From comment section:

Please pray for my dog, Butch. He's an 8 year old Min Pin with diabetes and cataracts. We took him to Cornell for a preliminary workup for cataract surgery. During the workup they found out that Butch has gallstones and a mass in his abdomen. The one gallstone is so large that there is a possibility it might block the bile duct causing the gallbladder to rupture. He is scheduled for surgery on Monday to have his gallbladder and the mass removed. Please pray for his safety during surgery, guidance for the surgeon's hands and a quick recovery for Butch.
